Hello
I recompiled U-BOOT that git tag is K2_UBOOT_2013_01_15.02_02 and I download evmk2h board.
I faced a big problem. U-BOOT don't loads linux kernel without UART.
When I connected UART and Boot the board Linux kernel is loaded fine. but removed UART, Linux kernel is not loaded.
When the board power is up, I have a delay a while, I connect UART to board. I have seen only U-BOOT Console.
actually problem is I can't see any message because UART is connected, and board power is up, working fine.
What I miss it? follow is my U-BOOT config.
